Are you looking to become a frontend developer or upgrade your skills with modern web technologies? This React Tutorial from Tpoint Tech is specially designed to help you Learn ReactJS for Beginners. We’ll walk you through the fundamentals of React—components, hooks, and state management—with simple code examples to get you project-ready in no time.

What is React?

React is a powerful JavaScript library developed by Facebook that helps you build fast, interactive user interfaces for web applications. It's widely used by top companies like Netflix, Airbnb, and Instagram.

If you're starting your frontend journey, our React Tutorial is perfect to Learn ReactJS for Beginners and build dynamic, component-based apps quickly and efficiently.

How to Set Up React

To begin coding in React, follow these steps:

Step 1: Install Node.js

Download and install Node.js if it’s not already installed.

Step 2: Create a React App

npx create-react-app my-app
cd my-app
npm start

This command sets up a fully working React project and starts the development server. You’re now ready to build!

Understanding Components in React

React is all about components. A component is a small, reusable piece of code that returns a UI element.

Functional Component Example:

function Greeting() {
  return <h1>Hello from Tpoint Tech!</h1>;
}

You can use this component inside your App.js:

import Greeting from './Greeting';

function App() {
  return (
    <div>
      <Greeting />
    </div>
  );
}

export default App;

Key Point:

Functional components are simple functions that return JSX.
They help you build modular UIs quickly.

This is your first real step to Learn ReactJS for Beginners.

Passing Data with Props

Props (short for properties) are used to pass data from one component to another.

function Welcome(props) {
  return <h2>Welcome, {props.name}!</h2>;
}

<Welcome name="John" />

This allows you to build dynamic components that change based on data.

Using Use State Hook (State Management)

React uses state to manage data that changes over time. In functional components, you manage state using the Use State hook.

Use State Example:

import React, { useState } from 'react';

function Counter() {
  const [count, setCount] = useState(0);

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>Click</button>
    </div>
  );
}

This example shows a counter that updates when a button is clicked. You’ll find state management in almost every React project.

Using Use Effect Hook (Side Effects)

Use Effect is another important hook used for side effects like API calls or DOM updates.

Use Effect Example:

import React, { useEffect, useState } from 'react';

function PostList() {
  const [posts, setPosts] = useState([]);

  useEffect(() => {
    fetch('https://jsonplaceholder.typicode.com/posts')
      .then(response => response.json())
      .then(data => setPosts(data.slice(0, 5)));
  }, []);

  return (
    <ul>
      {posts.map(post => (
        <li key={post.id}>{post.title}</li>
      ))}
    </ul>
  );
}

Summary:

useState manages data
useEffect runs code after rendering
Together, they allow you to create interactive and data-driven apps.

Basic State Management in React

Managing state becomes more complex as your app grows. Here are a few methods to handle state:

1️⃣ Lifting State Up

Move state to the common parent if two child components need to share data.

2️⃣ Use Context Hook

For small to medium apps, Use-Context allows you to share data globally.

const ThemeContext = React.createContext();

function App() {
  return (
    <ThemeContext.Provider value="dark">
      <Child />
    </ThemeContext.Provider>
  );
}

function Child() {
  const theme = React.useContext(ThemeContext);
  return <div>Theme is {theme}</div>;
}

Redux or Zustand (Advanced)

For large-scale applications, tools like Redux help manage complex global state in a predictable way.
